11 Claims.

My invention relates to the method of making expanding wallets,files, or portfolios; where the bottom and end walls are made in an accordion plait structure having a bellows-like nature to be expandable into different sizes for use.

The expanding Wallets or files are made with an inner wall of paper or a sheet material, and these are adapted to be covered by a reinforcing side wall of other material. The structure of the" 91 files or wallets is of a reinforced nature wherethe inner walls are first attached to the expanding gusset which forms the bottom and ends of the same, and then the outer reinforcing walls of avery tough and long-wearing material which are fusually of a paper construction, are attached to the outer surface of the inner'walls and" which cover the outer edges of the accordion plaited gusset. v

Heretofore these files, wallets or portfolios, have been made by hand and it is 'diflicult tohave them" folded and pasted uniformly' together. The purpose of my invention is to provide a method of making these files and wallets by a certain de- M fined method which will make eachwallet uniform in design and paste the parts together in unity so that all of the articles are of the" s'am'e generaluniform construction. f'

My method consists offirst'placing the sheets which form the inside of the file orwalle't in a 0 paster which-is adapted to place the paste on a defined marginal edge on three sides of the sheet When the marginal paste or adhesive is applied; to the sheet it is then-placed inside the outer foldsor edges of the accordion plaited gusset andit is 1 5' then placed upon an endle'sscarrier which carries thesame into a compressor made up of alseries of compressing rollers which extend over the table over which the endless carrier travels-L Whe'n' the file or portfolio comes outof this-compressor'on' Q the carrier it is then picked up, and sheets" which are pastedover a defined surface to'equal' the" area of the sides already attached inside of'the plaited gusset are placed orf-theoutside of the same'so as to forrh the front outside walls of the file, wallet or portfolio; and the same is then placed on an endless carrier which; carries the same into; a compressor over atable andjupon emerging fromthis carrier the files-or wallet's'are complete with ends and the bottorn 'accordion plaited portions and inside: and outside walls pasted together so that'the edgesofthe accordion plaited ends of the bottom'are'pastedhetween'the' inneriand louter sidewalls.

Figure 20 is the belt tightener for the conveying belt which operates under the compressing roller belt.

My method is carried out in a manner to make expanding portfolios, files and the like, so that each will be uniform and in a manner to produce the same rapidly rather than by the hand method where each file or portfolio had to be folded and squeezed into a press.

In carrying out my method the first gluing operation for the sheets is accomplished by the gluing machine A which places a marginal glue strip by the gluer 10 on the sheets 11 about three 3 sides of the same, as illustrated by the dotted marginal lines 12 in Figures 3 and 4. These sheets such as 11 for the large size and 11 for the small size are then placed on the inside of the outer folds of the gusset member 14 and the file or portfolio B in its form illustrated in Figure 7 is laid upon the carrier belt which carries the same into the compressor 0.

The compressor C includes a series of compressing rolls 16 which are held on their ends in the slot bearing 17 and by means of the spring 18 the rolls 16 are held under tension against the under side of the endless belt 19 which goes around the roll 16. The structure of the sliding bearing for the end of the rolls 16 is illustrated in enlarged view in Figure 18. The belt 15 extends under the belt 19 and the rolls l6 and bears against the rigid table top 20. One end of the belt 15 is carried by the roll 21 and the other extreme opposite end is carried by the roll 22. A suitable motor 23 operates the roll 22 so as to operate the belt 15 and the belt 19 operates by friction with the belt 15. An idle roll 24 is provided for the belt 15 and a tightening roll 25 adjacent the idle roll 24 is adapted to take care a of the slack or adjustment in thebelt 15.

Each spring 18 forces downwardly the opposed end bearings of the rolls 16, pressing these rolls downinto contact with the portion of the belt 19 beneath the same, and urging this belt against the belt 15 and against the table 20. As the parts of the file or portfolio B are carried between the belts 15 and 19 they raise the rollers 16 directly above the file, compressing the springs 18. The belt 19 is thus retained under spring tension against the portfolio B, continuously compressing the file B and repeatedly accentuating the compression as the file moves directly under one of the rolls 16.

Work tables 26 are provided on each side of the starting end 15' for the belt 15 and the girls who place thesides 11 and 11' in the plaited or bellows-like gusset member 14 work on these tables andthen place the file B on to the belt 15 when it is ready to be compressed in the compressor C. The top table 27 between the tables 26 which are positioned on each side of the starting end 15 of the belt 15, provides a storage for folded bellows or gussets 14 for the workers at the tables 26. The compressor C is of sufficient length to firmly set the glue which holds the parts together of the member B, so that when these articles B come out of the compressor they may drop into a container D where they are stored until the next operation.

A belt tightener E for the belt 19 is illustrated in enlarged detail in Figure 19 which includes an adjusting bolt 28 which operates to draw the end roller 16 in a manner to tighten the belt 19.

The tightening pulley 25 is operated in either direction by the adjusting screw 29, as illustrated in Figure 20, so as to move the roller 25 in the slotted bearing 30 to adjust the slack of the belt 15.

The section of Figure 17 shows the compressor of the second operation of my method and I have termed this compressor C. This compressor C is of the same general construction and nature as the compressor C and by means of these two compressors, work tables, and carrying belts which are positioned conveniently adjacent to each other in a similar manner as illustrated in the plan view in Figure 15, my method may be carried out to complete the expanding portfolios, files and wallets.

When the first operation has been complete to secure the inside members 11 and 11 to the expanding bellows or gusset 14, and they are discharged in the container D, they are then taken over to the top or storage table 27' and are stored on this work table 27 so that the workers on each 1'15, side of the tables 26' may apply the outside walls to the file or wallet.

The method is then continued by passing the outer sheet 32 through the gluer F so as to apply glue over the entire surface such as 33, illustrated in Figure 9 by the dots over the surface. This sheet 32 is then applied tothe large inside sheet 11, as illustrated in Figure 10. Then a second outside sheet 34 is passed through the gluer F in a manner so that it will be held by the guard 35 120 to apply glue over the surface 36 illustrated by the dots on the surface in Figure 12. The area of the surface 36 is virtually the same as the surface of the small sheet 11 and then the sheet 34 is laid on the outside of the inner small sheet 125 11, as illustrated in Figure 13, and the operator then lays the expanding portfolio file or wallet G on the starting end 15' of the compressor C and it is carried into the compressor C which compresses the same in a manner to set the adhesive by the time it is discharged out into the container H. The complete portfolios or files G are thus delivered in rapid succession into the container H, all in a uniform formation and with the parts tightly adhered together. This completes the portfolio or expanding file G in a simple and effective manner and much more economically than they can be manufactured by hand and where they are placed in a press to squeeze them long enough to permit the adhesive to set so that the parts will not separate in the making of the same. In making these files and portfolios by hand where they are squeezed together in a press, the manufacturing costs make the prices to the customer virtually prohibitive of 5 general use. A- portfolio or file of this nature is very desirable and with my method I accomplish a long desired result to provide portfolios, files or other articles of the nature set forth at a'reasonable price so as to permit'their general use.

Thus my method consists in attaching the parts of an expanding wallet, file or portfolio, by applying adhesive and then passing the same through a compressor carrier which holds the parts compressed until the adhesive has set. My method is carried out in a simple and effective manner and overcomes the old method of making expandable portfolios andfiles by hand, permitting them to be made virtually automatically in the sealing and securing of the parts together, and while I have illustrated and described the method in accordance with the patent statutes, suggesting certain means of carrying out the method, I desire to have it understood that variations can be made and the same applied to other uses within the scope of the following claims without limitation as to the purpose and intent of the invention.

I claim:
